[oi-dev] Recent /dev a9 repository ?

[Udo Grabowski (IMK)]

Hi again,

(I really hate it to reply to my own posts, but there seems
to be no one else left willing to reply...)

Amojng the numerous different older and newer pages on how
to compile illumos or OI with or without gcc or Sun cc and
with this or that version I found this page today where
SunStudio 12.3 is mentioned as the compiler now to be
used (when stuck with Sun cc):
<http://wiki.openindiana.org/oi/Building+with+oi-build>

Can anybody confirm that this is the version oi_151a9 was
built with ? Or can anybody tell me if there's a trace of
the compiler version left in any of the binaries on oi_151a9 ?
